The sand tiger shark is a truly impressive species, and you can see it right here with your own eyes at Deep Sea World. So, just what is a sand tiger shark, and what are some of its characteristics? Let’s find out.
What are sand tiger sharks?
The sand tiger shark (Carcharias taurus) is also known as the grey nurse shark or ragged-tooth shark, depending on where in the world you are. They can look very aggressive, with sharp, protruding teeth and large bodies, but they are in fact quite docile.
The sand tiger shark is now the only living member of its genus, but does belong to a wider family of sand sharks known as Odontaspididae. Interestingly, the sand tiger shark is actually related to the great white shark, as they both belong to the order Lamniformes.
They got their name from living nearer the shore, and their big appetites!
You’d be forgiven for thinking that sand tiger sharks are the same as tiger sharks, but they are actually two very different species. The tiger shark (Galeocerdo cuvier) are commonly found in tropical waters and have been known to grow over 4 metres long, making them much bigger than the sand tiger shark. Their name comes from the dark, vertical stripes found on their body, which fade as the sharks mature.
What do sand tiger sharks look like?
Sand tiger sharks are typically a brownish-grey in colour, with a white underbelly. You might also notice rust-coloured spots along their back. These sharks have a flattened, cone-shaped nose. Their tail is quite distinct, with a notched upper lobe that is much longer than the lower lobe.
Sand tiger sharks can grow up to 3 metres in length, and weigh up to 158kg. Another striking feature of the sand tiger shark is their rows of jagged, sharp teeth, which protrude in all directions and can be seen even when their mouths are shut!
Where do sand tiger sharks live?
Sand tiger sharks much prefer living in shallower waters near the shore, typically in areas like shallow bays and coral or rocky reefs. You will find sand tiger sharks almost all over the world, as they live in warm to tropical oceans, with the exception of the eastern Pacific.
What do sand tiger sharks eat?
Sand tiger sharks feed at night, staying close to the bottom of the water to hunt their prey. They have been known to feed on fish, but also smaller rays and other sharks. They will also eat crustaceans and squid.
In some instances, sand tiger sharks will hunt in groups, or shivers, by surrounding shoals of fish and picking them off with speed.
Additional facts about sand tiger sharks
Sand tiger sharks are fascinating creatures, and there’s even more to learn about them than what we’ve already covered. Here are just a few extra facts to make sure you know your stuff when it comes to this species:
Unique swimming technique: Sand tiger sharks have the ability to float motionlessly in the water, which is perfect for lying in wait for their prey. They come to the surface and swallow air, which fills their stomach and creates more buoyancy.
Slow-moving: Despite their size and prowess, sand tiger sharks are actually quite slow and sluggish in their movement. The species is particularly placid and will only attack if provoked.
Electroreceptors: Like other shark species, the sand tiger shark can detect electrical current of their prey using electroreceptors, which are in their snouts.
Reproduction: Sand tiger sharks have one of the lowest reproductive rates among sharks, and might only give birth to one or two pups every 2-3 years. They give birth to live young.
Sand tiger shark population
Unfortunately the sand tiger shark is classified as critically endangered, with numbers still declining around the world. As well as their slow reproductive rates, sand tiger sharks are also vulnerable to even the smallest of population pressure.
It’s so important to do as much as we can to ensure their future. This can be done through making sustainable and eco-friendly choices, such as conserving water, preventing rubbish from entering our waterways and being sure to recycle or use reusable items instead of single-use plastics.
